Abstract
The utility model relates to the field of a single screw air compressor, in particular to a 'medium-pressure single screw air compressor capable of realizing a discharge pressure of 2.0 M Pa to 6.0 M Pa through a single-stage compression under normal conditions'. A meshing pair composed of a cylindrical screw and two plane star wheels arranged in a central symmetrical mode is arranged inside the casing. A screw spiral groove, a casing inner wall and star wheel teeth form a closed element volume which is changed along with movement of the star wheel teeth. Air enters spaces between screw teeth through an air suction cavity, is closed and compressed to reach a designed pressure and is discharged from a triangle discharging port arranged on the casing inner wall. The single-stage medium-pressure single screw air compressor has the advantages of realizing the discharging pressure of 2.0 M Pa to 6.0 M Pa through the single-stage compression under the normal conditions, simplifying a structure of a compressor unit, and being more practical, simpler and more energy-saving compared with compressors realizing the discharging pressure of 2.0 M Pa to 6.0 M Pa through a two-stage or more-stage compression.
